First off, i like to say, i've done the cablenut tweaks, virus check, spyware check, and all of that. Doesnt do anything, and this is really annoying. I am running the Scientific Atlantic modem that came with the service. I should be getting btwn 4-6Mbps. When i first got it, it ran around 5Mbps. If you know whats wrong plz tell me.

Well i called them up, and the guy who talked to me said, they might be doing some maitenence around where i live, and that my speed would only be down for probably tonight. Although i do suspect thats just what he told me to get me off the phone, i guess ill wait till tomorrow morning to see whats up.


Thanx for the help anyways though. Hopefully this will all be solved by tomorrow.

I took off the cablenut tweaks and it works a little better. But if you have any custom recommendations i can try them again.
